Method Detail

initScriptFunction

public final void initScriptFunction(Context cx,
                                     Scriptable scope)

getLength

public int getLength()

Overrides:

getLength in class BaseFunction

getArity

public int getArity()

Overrides:

getArity in class BaseFunction

jsGet_name

public java.lang.String jsGet_name()

Deprecated. Use BaseFunction.getFunctionName() instead. For backwards compatibility keep an old method name used by Batik and possibly others.

getEncodedSource

public java.lang.String getEncodedSource()

Get encoded source string.

getDebuggableView

public DebuggableScript getDebuggableView()

resumeGenerator

public java.lang.Object resumeGenerator(Context cx,
                                        Scriptable scope,
                                        int operation,
                                        java.lang.Object state,
                                        java.lang.Object value)

Resume execution of a suspended generator.

Parameters:

cx - The current context

scope - Scope for the parent generator function

operation - The resumption operation (next, send, etc.. )

state - The generator state (has locals, stack, etc.)

value - The return value of yield (if required).

Returns:

The next yielded value (if any)

getLanguageVersion

protected abstract int getLanguageVersion()

getParamCount

protected abstract int getParamCount()

Get number of declared parameters. It should be 0 for scripts.

getParamAndVarCount

protected abstract int getParamAndVarCount()

Get number of declared parameters and variables defined through var statements.

getParamOrVarName

protected abstract java.lang.String getParamOrVarName(int index)

Get parameter or variable name. If index < getParamCount(), then return the name of the corresponding parameter. Otherwise return the name of variable.

getParamOrVarConst

protected boolean getParamOrVarConst(int index)

Get parameter or variable const-ness. If index < getParamCount(), then return the const-ness of the corresponding parameter. Otherwise return whether the variable is const.
